Abstract: Described herein are methods and apparatus for spectroscopic analysis of samples. In many embodiments, an apparatus for providing spectroscopic analysis of a sample comprises a sample holder. For example, the sample holder may comprise a consumable single use sample holder that can be readily coupled to and removed from a measurement apparatus such as a spectrometer. The sample holder may comprise a measurement surface configured to receive the sample during measurement, wherein the measurement surface may comprise a porous mesh. The porous mesh can receive the sample to optimally configure the sample for spectroscopic measurement, as described in further detail herein.

Abstract: Methods, apparatus and/or systems are disclosed for collecting and processing of spectral data from an object to enable the determination of the presence and/or amount of a target analyte present in the object is disclosed. The object may be a portion of a person's body such as the forearm, palms, fingers, or eye. The target analyte may be ethanol. The method/apparatus/system for performing such spectral data collection may include one or more broadband emitters such as thermal emitters (aka “black-body” or “gray-body” emitters), incandescent sources, light emitting diodes, and the like.

Abstract: Blood glucose levels in an individual are determined by aligning a region of the retina of the eye of an individual with an instrument, measuring a regeneration rate of the retinal visual pigment of the individual, and using the measured regeneration rate to calculate the blood glucose level. The apparatus for measuring the blood glucose comprises a blood glucose analysis instrument adapted to determine blood glucose concentration from information regarding regeneration rate of the visual pigment in the retina region of an eye, and an alignment mechanism adapted to align the retina region with at least a portion of the device.

Abstract: An apparatus carries out measurements of blood glucose in a repeatable, non-invasive manner by measurement of the rate of regeneration of retinal visual pigments, such as cone visual pigments. The rate of regeneration of visual pigments is dependent upon the blood glucose concentration, and by measuring the visual pigment regeneration rate, blood glucose concentration can be accurately determined. This apparatus exposes the retina to light of selected wavelengths in selected distributions and subsequently analyzes the reflection (as color or darkness) from a selected portion of the exposed region of the retina, preferably from the fovea.
